Fort New Casco(1698 - 1716), Falmouth Foreside
A large 70-foot square earthwork and palisaded fort, also known as Casco Fort, with an Officers' quarters, storehouse, and guardhouse. It was attacked by the French in 1703, rebuilt and enlarged in 1705 as an oblong square 250 feet long and 190 feet wide, with a supporting blockhouse at the shoreline. It was demolished by the Massachusetts government due to budget cuts. Some earthworks may still exist on private property (on Old Powderhouse Road ?).

¤¤ Fort Loyal (1676 - 1690), PortlandFORT WIKI
A palisaded log fort. Also spelled Loyall. Rebuilt and enlarged with four blockhouses and eight guns in 1690, but could not withstand the attack by the French that year, and was destroyed. Eventually rebuilt and renamed Falmouth Fort in 1742, located at the foot of present-day India Street. An earthwork was built here in 1775, called the Lower Battery. Nothing remains. Nearby were the Upper Battery (1776) at the upper end of Free Street, and Magazine Battery (1776) at Monument Square. Neither exists today.

Originally a Patriot five-gun half-moon battery in 1775. Rebuilt by the state militia in 1814, it was enlarged and enclosed with a magazine and barracks. The earthworks still remain at the Eastern Promenade at Fore Street. Two 1867 seige guns were placed there much later for display purposes.

¤¤ Fort Lawrence (1814 - 1815), Portland

Camp Berry(1861 - 1865), South Portland
A Civil War recruitment and training camp originally located on Mackworth (Mackey's) Island at the mouth of the Presumpscot River in Falmouth, known as Camp Butler. It was relocated to the Cape Elizabeth Trotting Park in 1862, located along Long Creek and the Fore River in Ligonia, and was renamed Camp King and later Camp Abraham Lincoln. Renamed again in 1863. The post hospital was established on Mackey's Island in August 1863, then relocated to Camp Berry proper in November 1863. The hospital was closed in September 1865. Eleven two-family houses were used as Officers' quarters, and ten one-story wooden barracks were built for the enlisted men. The site became the location of the Portland Rolling Mills in 1866. Several of the houses and/or barracks remained in use for factory workers. The site is now a modern tank farm at the end of Lincoln Street, near the Veterans Memorial Bridge (US 1).

¤ Fort Preble
(Portland Harbor Museum)
(Southern Maine Community College)(1808 - 1947), South Portland
Originally this was a 14-gun star-shaped earthwork and stone fort. Built on the site of Patriot Spring Point Battery from 1776, which was renamed Fort Hancock in 1778. The 12-gun North Battery and 10-gun South Battery were built in 1845 and rebuilt again (33 guns total) in the 1870's with new magazines. The South Battery was enlarged to 24 guns in 1887. The outer casemates along the seawall were built in 1863, and the brick face of the old fort was covered with granite. The fort was unsuccessfully attacked in June 1863 by a Confederate raider ship, the Archer. Seacoast batteries here were Battery Kearny (1901 - 1942) destroyed, Battery Chase (1901 - 1942) destroyed, Battery Rivardi (1906 - 1917) built on top of the old fort, Battery Mason (1906 - 1942), and New Battery Mason (1942 - 1946) eroded away from the cliff face. AA Battery #1 (1921 - 1945) was emplaced on Battery Rivardi. A detached 37mm AMTB battery (Battery 361) was also located on post during WWII. Many of the post buildings are still in use by Southern Maine Community College, which acquired the land in 1952. The remaining concrete support shaft of the former Fort Command observation station (1906) is now a Coast Artillery Memorial. The former Ordnance Machine Shop (1902) is now used by the Portland Harbor Museum. The Spring Point Ledge Lighthouse was built in 1897, and the stone breakwater was built in 1951.

Located at Portland Head, this was a subpost of Fort Preble until 1894, originally named Portland Head Military Reservation. The 17-gun Battery at Portland Head was built in 1873 - 1876, but never finished. A few surviving gun mounts and magazines still exist next to Battery Hobart. An early mine casemate was built in 1891, remodeled in 1903. Camp Burdette was located on the future parade ground during the Spanish-American War (1898), garrisoned by Connecticut state troops on Coast Reserve duty. The fort was formally named in 1899. In 1899 an unnamed battery of one 6-inch Armstrong gun was emplaced on the 1873 battery, which later became Battery Hobart.

A disappearing searchlight emplacement (1920) was located behind Battery Garesché. The central powerhouse (1907) and protected post switchboard (1920) (buried) still exist near the main gate. The mine casemate still exists below Battery Hobart, near the ruins of the mine tramway and wharf. It was used until the late 1990's as a Civil Defense shelter. The WWII HECP/HDCP with an SCR-582 radar was also located on post. A semi-permanent National Guard tent camp was established here in 1930. The Air Force briefly installed an AN/TPS-1B LASHUP radar here on post in 1950-51. All battery observation posts and fire-control stations were removed before 1960. Became a town park open to the public in 1979. A few of the old post buildings still survive. The Fort Williams Memorial is located at Battery Blair. The ruins of the Goddard Mansion (1858) are located near Battery Keyes. The Portland Head Lighthouse was built in 1790. Admission fee to the lighthouse museum.

A Navy signal station and operating base was also located here during WWII. There were many observation and command stations here before development began on the housing community. Most of the former post buildings still survive, converted to upscale housing units, although several are still derelict. Several of the surviving observation stations have also been converted to modern housing units. Most sites are private property. Public areas include the dock landing, restaurant, museum, and general store, all converted from original post buildings.

¤ Long Island Military Reservation(1917/1942 - 1946), Long Island

Nearby outside of the park, the west tower of the Cape Elizabeth Two Lights (built 1874) was discontinued as an active light in 1924, and was converted in 1942 into a fire-control station (private property since 1959). An SCR-296A radar was located on Dyer Point below the lighthouses. A steel-frame fire-control tower for Battery Foote (Fort Levett) was built in 1927 on Blue Hill near Broad Cove (no remains).

¤ ALSO: A detached 37mm AMTB battery (Battery 370) was located at Drinkwater Point in Yarmouth, opposite Cousins Island, during WWII. A four-gun 155mm gun battery was located at Biddeford Pool(see page 4). Underwater minefields in WWII were located between Portland Head and Cushing Island, and between Peaks Island and Long Island.
